摘要
The invention describes an active fluid cooling device for cooling of electronic devices, which comprises a housing in which a cavity is incorporated, wherein the cavity of the housing is divided by a first piezoelectric actuator and a second piezoelectric actuator which each have a planar form into three chambers, wherein the first piezoelectric actuator defines together with the housing an upper air chamber, wherein the first piezoelectric actuator together with the second piezoelectric actuator and the housing defines a middle air chamber, and wherein second piezoelectric actuator together with the housing defines a bottom air chamber, wherein the upper air chamber is in cooperation with an upper opening of the housing and wherein the middle air chamber is in cooperation with a middle opening of the housing and wherein the bottom air chamber is in cooperation with a lower opening of the housing, wherein a positive electric potential and a negative electric potential are applied in alternating way to the two piezoelectric actuators in such a way that the volumes of the upper air chamber, middle air chamber and bottom air chamber within the cavity of the housing are changing to result in a fluid stream in and out of the openings of the housing, so that the generated fluid stream is usable for cooling a heat generating element of an electronic device.
